Radiofrequency Catheter Ablation (RFCA) is a medical procedure used to treat certain cardiac arrhythmias, or irregular heart rhythms, by using high-frequency electrical energy to destroy abnormal tissue in the heart. This technique involves the use of a thin, flexible catheter that is guided through blood vessels to reach the heart. The catheter contains a small electrode at its tip that emits radiofrequency energy when activated.
During the RFCA procedure, the catheter is carefully positioned within the heart, and the electrode delivers controlled radiofrequency energy to create localized heat. This heat destroys the abnormal tissue in the heart responsible for the arrhythmia. By eliminating or modifying the electrical pathways causing the irregular rhythm, RFCA helps restore the heart's normal electrical conduction.
Radiofrequency Catheter Ablation is a minimally invasive procedure that offers several benefits over traditional surgical methods, such as open-heart surgery. It is performed under local anesthesia, reducing the risks associated with general anesthesia. RFCA also has a shorter recovery time, allowing patients to resume normal activities sooner.
RFCA is commonly used to treat conditions like supraventricular tachycardia (SVT), atrial fibrillation, and atrial flutter. It provides a long-term solution for patients with recurrent or drug-resistant arrhythmias, improving their quality of life and reducing the need for ongoing medications. While RFCA is generally safe and effective, there are some risks involved, such as bleeding, infection, or damage to nearby structures. However, the benefits of this technique often outweigh the potential complications, making RFCA a valuable treatment option for individuals suffering from certain cardiac arrhythmias.
